Modification of Subsurface Structure in TiC-(Ni-Cr) Cermet Composite under Pulsed Electron-Beam Irradiation of Samples in Plasmas of Light and Heavy Inert Gases

摘要

Experiments with metal ceramic alloys with various ceramic content proved that the performance degree of pulsed electron-ion-plasm a irradiation as a technology of creating a surface layer multilevel structural phase condition, where particles are measured within a nano dimensional diapason, depends on ionization energy degree as well as on plasma-supporting gas atomic weight. When ionization energy falls parallel to plasma-supporting gas atomic weight growth, ceramic component particles dissolve in a metal binding melt more quickly, and an accelerated dispersion of ceramic particles to nano sized level can be observed. A multilevel structural phase condition causes friction ratio decrease, while a metal ceramic alloy surface layer wear ability increases many-folds.
